Two days ago my work email delivered every email that I had ever sent to my BB Curve. The dates went back to August 2008. I turned on my BB and watched the emails populate. I then deleted them all and had no more happenings until this morning.

This morning the same thing happened but once they populated my BB, they then were automatically deleted (I pushed no buttons)

-I have OS 4.5.0.110
-I upgraded to 4.5 when it was first available and just now had this happen
-I have TWO email accounts: 1) Microsoft Outlook (work email that this happened with) and 2) Yahoo - this situation didn't happen
